Title: Variable focus optical system
Inventor: HASHIMOTO KAZUE
IPC: G02B15/00
Filed: 1986-07-17
Abstract: PURPOSE:To prevent an image from the change of its power even if a focus position is changed by arranging a polarizing plate and a transparent ferroelectric plate whose refractive index is changed in accordance with an impressed voltage in an optical path and connecting a variable power supply for impressing a variable voltage to the ferroelectric plate. CONSTITUTION:It is supposed that light projected from light source is led into the optical system and the focus of a lens B3 is positioned on 8a'. Since a corner part 8a is to be observed, the focus of the lens B3 should be adjusted from the 8a' to 8a. When an electric field, i.e. a voltage, is impressed to the ferroelectric plate 15 on a variable refractive index plate B5 is impressed by the variable power supply B7, a linear electro-optical effect is generated and the refractive index of the ferroelectric plate 15 is changed. If the voltage is properly set up, the converging optical path is changed from a dashed line to a solid line in accordance with the change of the refractive index and the lens B3 can be focused on a required corner part 8a.

Abstract: PURPOSE:To prevent the lateral diffusion of phosphorous during emitter diffusion by a method wherein the emitter diffusion window-base electrode window poly Si is isolated by etching. CONSTITUTION:An epitaxial layer 12 is grown on a P type Si substrate 11 by forming an N<+> buried layer, and an isolating oxide film 13 is formed by thermal oxidation, using Si3N4 as a mask. After removal of the Si3N4, a thermal oxide film 14 is grown over the whole surface, and the base region is formed by B+ ion implantation; thereafter, a CVD-SiO2 film 15 and a CVD-Si3N4 film 16 are grown. An emitter diffusion window and a base electrode window are formed by dry-etching the films 14-16, and next a CVD-poly Si17 and a CVD-PSG18 are grown. The PSG on the base electrode is wet-etched by pattering the resist 19, and B<+> ions are implanted to the base electrode window. The emitter diffusion window-base electrode poly Si is isolated by wet etching. The emitter region is formed by heat treatment, and electrodes are evaporated after removal of the PSG.

Abstract: PURPOSE:To withstand a high centrifugal force with a greater workability by resin molding a conductive pipe with a split groove formed thereinside in such a manner that both ends thereof is buried into the resin as fixed section after the circumference of the ends is cut properly. CONSTITUTION:An internal split groove 2 of a commutator piece is formed axially inside a conductive pipe 1 made of a copper or the like. After the conductive pipe 1 is cut to a proper length, both ends thereof are cut properly on the circumference so much as to expose the split groove 2, where a fixing projection piece is formed. Thereafter, a resin fills the inside of the conductive pipe 1 and the circumference of the fixing projection piece 3 in such a manner that the fixing projection piece 3 is fully buried into the resin. A split groove 5 is placed into the circumference of the projection piece to make all commutators independent of each other electrically. This enables less working time and shorter process while making the commutator usable for equipment employing a greater centrifugal force.
